How Is AI Really Changing the Way We Work?
AI giant Anthropic turned its research lens on itself.
In August 2025, they conducted a survey of 132 internal engineers and researchers, supplemented by 53 in-depth qualitative interviews and analysis of internal Claude Code usage data, attempting to reveal AI’s true impact within their own company.
The research findings paint a picture of profound transformation: the nature of software developers’ work is being fundamentally changed, with hope and concern coexisting side by side.
Engineers’ productivity has dramatically increased, they’ve become more “full-stack,” learning and iteration speeds have accelerated, and they’ve even begun tackling tasks previously overlooked.
But this expansion in breadth also brings trade-offs: some worry this may lead to a loss of deep technical capabilities or an inability to effectively supervise Claude’s output; others embrace the change, believing it allows them to engage in higher-level thinking.
Some have found that increased collaboration with AI means decreased collaboration with colleagues; others are beginning to wonder whether they’ll eventually be replaced by automation tools.
This research focused on a company that builds AI, whose engineers already enjoy the privilege of accessing cutting-edge tools, but Anthropic believes that the changes happening internally may foreshadow broader social transformation.
The models used in the study were Claude Sonnet 4 and Claude Opus 4.
